Problem with LCD and PIC16F877A
PostPosted: Thu Aug 11, 2005 1:14 pm     Reply with quote
Hello Everyone !!!!

I am working with PIC16F877A and i try put something character for the LCD and it does not work. The LCD is PC1602F and is 2x16 lines.I use the driver that this in compiler , #include<LCD.c>. There are no errors in the compiler.I adjust the contrast.The conections are done correctly,
D0=unused D1= rs D2=rw D3=enable D4=D4 D5=D5 D6=D6 D7=D7.
This is my code:

Code:


#include <16F877A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP,PUT,BROWNOUT
#use delay(clock=20000000)
#include<LCD.c>

void main()
{
  lcd_init();
  while(1)
    {
      lcd_gotoxy(1,1);
      printf(lcd_putc,"Hello,");
      lcd_gotoxy(1,2);
      printf(lcd_putc,"World!");
      delay_ms(100);
    }
}
 


Because it does not work????????

Those are not the connections given in the CCS LCD.C driver.
The driver says this:
Quote:

// D0 enable
// D1 rs
// D2 rw
// D4 D4
// D5 D5
// D6 D6
// D7 D7
